Define tautology
Solution
A tautology in logic is a compound statement that is always true, no matter what the truth values of the individual statements that comprise it. It's a statement that is composed in such a way that it cannot be false under any circumstances. For example, the statement "It will rain today or it will not rain today" is a tautology because there are no other possibilities - either it will rain or it won't.
